Hi,
I'm getting a null pointer exception from Aspectwerkz code during hot deployment in Tomcat 4 container. This happens when I try to deploy an aspect when the server is running . The same process works fine in Tomcat5. Here's the complete log :

I saw this piece of code from an online repository, looks like the aspectwerkz is faling to retreive the hashcode of the classloader. The same deployment log in Tomcat 5 looks like :
Deployer::INFO - deploying aspect [net.sf.infrared.aspects.api.DomainAPIAspect]] in class loader [WebappClassLoader
delegate: false
repositories:
/WEB-INF/classes/
----------> Parent Classloader:
org.apache.catalina.loader.StandardClassLoader@19bb25a
Does tomcat 4 require any different configuration compared to tomcat 5 ?
Any pointer on this will be highly appreciated.
Thanks
